"The game I play is a very interesting one. It's imagination in a tight straightjacket, which is this: that it has to agree with the known laws of physics. [...] It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, it's allowed, according to what's known, okay?"

How our brains may have evolved for language, and clues to what makes us leaders—or followers

Your browser does not support the audio element.

Yes, humans are the only species with language, but how did we acquire it? New research suggests our linguistic prowess might arise from the same process that brought domesticated dogs big eyes and bonobos the power to read others’ intent. Online News Editor Catherine Matacic joins host Sarah Crespi to talk about how humans might have self-domesticated themselves, leading to physical and behavioral changes that gave us a “language-ready” brain.
Sarah also talks with Micah Edelson of the University of Zurich in Switzerland about his group’s research into the role that “responsibility aversion”—the reluctance to make decisions for a group—might play when people decide to lead or defer in a group setting. In their experiments, the team found that some people adjusted how much risk they would take on, depending on whether they were deciding for themselves alone or for the entire group. The ones who didn’t—those who stuck to the same plan whether others were involved or not—tended to score higher on standardized tests of leadership and have held higher military rank.
